NAME

Tk_MainLoop - loop for events until all windows are deleted

SYNOPSIS

#include <tk.h>
Tk_MainLoop()

DESCRIPTION

Tk_MainLoop is a procedure that loops repeatedly calling Tcl_DoOneEvent. It returns only when there are no applications left in this process (i.e. no main windows exist anymore). Most windowing applications will call Tk_MainLoop after initialization; the main execution of the application will consist entirely of callbacks invoked via Tcl_DoOneEvent.

KEYWORDS

application, event, main loop
